SO doesn't get it

He doesn't understand why when he starts treating me different I think there's another woman. WHAT ELSE AM I SUPPOSED TO THINK ? Like I said to him last night, if I'm not getting your good side apparently someone else is.

But he insists it's my fault b.c I have an attitude and treat him bad and am always sick so he doesn't want to touch me unless I say to.....BULLSHIT. I'm fucking pregnant, but apparently that's not an excuse I guess. I admit I'm quick tempered, but he should be trying harder to understand and/or calm me not make me madder!! Weeks ago he was doing so good, and here we are back at the same place we always end up, just fighting and having attitudes. Smh I can't take it anymore, I don't know what to do or say to get us back where we were a couple weeks ago. He said he'd try to treat me better and was and now here we are again but if I say anything it's my fault. I'm treating him bad.
